I just linked Rachio with GH, and found that everytime I call out Rachio it does the whole overview before I can issue a command. How can I change this to have it say something else or not say anything at all?

You didn’t happen to say “to” after the “Hey Google, ask/tell Rachio”? I think that makes Home think you are trying to send a message. So “Hey Google, ask/tell Rachio to water front lawn” would not work but “Hey Google, ask/tell Rachio water front lawn” would.

Rachio to water front lawn" would not work but “Hey Google, ask/tell Rachio water front lawn” would.

Leaving the “to” out seems to allow some commands. IE “Hey Google, ask Rachio water front lawn” as you said.

It’s still pretty new I don’t think Google figured all the hiccups out yet. Sometime it would respond to Tell while other times it’ll be confuse and only respond to ask. Not important as Rachio was meant to be hands off anyways. Thought it’d be a cool conversation item with guests.
